Within a given field, whenever conflict between two parties arises, their sway is given by their respective influence within the field. The spoils and losses are both likewise reaped in that influence, and inversely proportional to the party's influence in relation to its opponent.
That, I believe, reflects what Mur has stated, though I may be mistaken. That, I assume, in the context of other recent posts.

That, however, is only entirely true in a white room scenario, where only that field and those two parties exist, such that the field cannot expand or lose ground, nor can the parties, other than to one another.
In other words, while I do think it accurately describes a tendency in social relations , it would be an oversimplification to assume it accurately describes them in their entirety.

There are many layers we can add to that statement. For instance:
A. the conflict for influence requires, itself, the investment of influence. As two parties are engaged in a conflict, they and their dominant field may be at their most vulnerable.
B. influence from outside a field can be used to accrue influence in another field. The gain of influence within a field may translate to the loss of influence within another field.
C. when a party uses a field's influence within another field successfully, it devalues the destination field's influence and increases the relative worth of the origin field's influence.
D. parties never seek influence in a single field, to the exclusion of all else. Fields, though they may have their unique characteristics, are never entirely unique.
E. a field is at its most influential when other fields fights over the right too interpret its symbolic capital according to their own internal paradigms, without, however, questioning its symbolic capital.
And even then, those are only broad descriptions which, though they accurately represent behaviorist tendencies in social conflicts, come short of accurately describing individual cases; good models, albeit models nevertheless.

The individual - anyone here, for instance - is already the individual case of the individual case in one such a model. One may reduce fields to institutions, those to individuals, and yet these to other categories of perception, and the more removed one from another, all the more insurmountable the task.
Accurately describing the individual through sociology, as opposed to institutions, or accurately describing institutions through psychology, as opposed to the individual, are things we are very distant from; and that is without getting into the meta-analysis of those categories.
